Contact Form clutter with share icons

I am trying the Contact Form in Jetpack for the first time.

I like how it works, and the ability to customize it.

However, there is an issue that has me stumped. There is a small rectangle of share icons off to one side, and most annoyingly also in the email field.

None of the icons in the row are clickable, and its appearance in the email field of the contact form makes it very difficult for a visitor to type in an address.

I have turned sharing on and off, in both the theme, and Jetpack. All to no avail. See it here:

Anyone with ideas on where to look next?

thanks

XML-RPC server accepts POST requests only.
